It also provides a tangible action that companies can take today in facilitating the energy transition, since based on the Paris agreement, energy efficiency can contribute to 37 % of the targeted reduction in CO2 emissions.
By promoting high-efficiency options that match the reliability and performance of lower-cost alternatives, the initiative aims to align long-term energy savings with sustainable industrial decision-making.
Milestones & challenges Since its launch in 2022, the TIE initiative has facilitated a shift towards enhanced energy efficiency. Industries with large electricity usage, such as air separation, have already set benchmarks by integrating high-efficiency technologies and prioritising energy savings.
TIE has seen marked success in renewable energy. For example, Ormat Technologies, a leader in renewable energy and a world-class developer in the geothermal sector, has adopted an ABB generator designed according to the TIE option for a geothermal plant in Indonesia. It has achieved an efficiency level of 98.7 % at unity power factor, helping the plant to minimize losses and optimize utilization of the geothermal energy source.
Based on Indonesia’ s current average energy mix, the site will save around 200,000 kgs of CO2 emissions annually.
It is important to note that in many projects the supply chain can be complex. This means that the operator, who will benefit ultimately from enhanced energy efficiency, is often not fully involved in the specification process and may even be unaware of the options available.
That is why a key aim of the TIE initiative is to promote pull-through from end-users.
Significant potential for energy savings ABB’ s TIE initiative proves its cost-effectiveness over time, although they are about 5 % more expensive initially due to their superior materials and designs, they usually pay for themselves within 0.5 – 3 years.
Future regulations, such as CO2 taxes, potentially enhance these financial incentives, making the shift to energy-efficient systems even more attractive.
An open invitation to raise efficiency The successful implementation of energy efficiency measures relies on pulling through end-user demand, so that prioritising energy efficiency can ripple through supply chains, encouraging an industry-wide adoption that advances climate goals. That is why we are happy to share our TIE methodology with any other manufacturer. This ensures that customers can have complete confidence that they can select the most efficient large motor or generator for their application without having to compromise on reliability, complexity, standards compliance and return on investment.
In essence, with TIE, customers have total transparency of information, so they know they really are comparing like with like. Most importantly, they will have all the data they need to make a fully informed decision on a major investment that will impact their business for the next 25 years.
